Systemmonitor entities returning Unavailable

Folks: I am new to HA and perhaps am making a novices mistake.
I installed HA in mid-July on a Raspberry PI4 and have been updating HA regularly since then.
I added the systemmonitor text to the config file as per the homeassistant web site systemmonitor configuration

Example configuration.yaml entry

sensor:

  • platform: systemmonitor
    resources:
    • type: disk_use_percent
      arg: /config
    • type: memory_free
    • type: processor_temperature

The types e.g. memory_free appear as entities

I created an entities card with the entities e.g. memory_free

For several days the entity values appeared with the correct numerical values but since late July
they appear as Unavailable

Perhaps a change in version made this change occur.

Could someone tell me how I need to change the config file or card so that the entity values are correctly displayed?

Thanks

Hi,

I had the same issue.
Make sure that you don’t have ‘sensor:’ twice in your configuration.yaml
If this is the case, remove a sensor and combine the values.
